NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Oct. 19, 1909.

To all whom it may concern:

Be it known that we, CARL W. SCHMIDT, of Piedmont, Alameda county,California, and ALEXANDER MACKIE, Jr., of Alameda, Alameda county,California, both citizens of United States, have invented new and usefulImprovements in Non-Refillable Bottles, of which the followingis aspecification.

Our invention relates to non-refillable bottles, and particularlybottles for use as shakers for removing the liquid contents, such assauces and the like.

Its object is to provide a simple, cheap, practical closure or stopplefor bottles, which, when once applied to any sort of a bottle after thebottle has been filled, will absolutely prevent the refilling of thebottle without the destruction of the latter.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which- Figure 1 is alongitudinal section, showing our non-refillable bottle. Fig. 2 is aside elevation of one of the halves forming the stopple, partiallybroken away. Fig. 3 is a similar view, showing the other half. Fig. 4 isan enlarged section on line X-X of Figs. 2 and 3.

Our invention comprises a stopple made in two parts or sections A and A.One of the sections, as A, is longer than the other, with a base portion2 of the full circumference of the stopple and forming an abutment forthe lower end of the section A to seat against when the parts areassembled. One of these sections, as A, is provided with a sinuousgroove 3 which forms, when the sections are assembled, an outlet for thedischarge of the liquid from the valve chamber 4. This valve chamber 4is inclosed by both the sections A and A, and the inlet to this valvechamber is through a tapered port 5 in the base ring 2. The valvechamber 4 is of sufficient size and shape to accommodate a flat, thindisk or wafer 6 which is preferably of some non-corroding material, asglass, and which has a considerable seating area on the bottom of thevalve chamber 4 when the bottle stands upright. The top of the valvechamber 4 around the opening into the discharge passage 3 is providedwith one or more bosses or projections 7 which operate to hold the disk6 sufficiently above the opening into the passage 3 when the bottle isinverted, so as not to interfere with the escape of the contents of thevalve chamber when the bottle is inverted.

The stopple portions A and A and the disk 6 may be of any suitable size,shape and material. Preferably these several parts are of glass, withthe members A and A cemented together after the disk 6 has been put inplace. Advantage has here been taken of the known property of a flatpiece of glass to cohere when moistened to a similar flat glass surface;the opposed surfaces being smooth, and when air is excluded, itbeingalmost impossible to lift one from the other. Consequently, in thepresent case, the opening of the flared port 5 into the valve chamber iscomparatively small with respect to the area of the disk 6, so that thedisk 6 has a substantial portion of its area normally resting on a flat,correspondingly smooth seat in the bottom of the valve chamber.

The opposing flat faces of the parts A and A are preferably providedwith some suitable interlocking means, as, for instance, the dowelprojections 8 on one member engaging the recesses 9 in the other member,so as to insure proper registration of the parts.

The sections A and A are suitably turned down between their ends toprovide an annular pocket which is preferably of irregular depth, toreceive a filling of cement, as 11; and if desired, the neck of thebottle may be provided with a bulge, as represented at 12, into whichthe cement is received to form an anchorage for the stopper.Furthermore, the tops of the sections A and A are provided with anoverhanging ledge or flange 13 adapted to seat on top of the mouth ofthe bottle, and so prevent the insertion of any instrument for thepurpose of removing the cork or digging out the cement, and a protectivegasket 14.

In operation, assuming the bottle to have been filled and the stopplesuitably inserted and anchored or cemented therein so as to render itimpossible to remove without actually breaking off the neck of thebottle, the contents may be discharged by inverting the bottle andgiving it a shaker efiect; the pressure of the contents on the underside of the disk readily releasing the latter from its seat, and theliquid flowing out around the sides of the disk and between the bosses 7and out through the sinuous passage 3. Of course, by making the bosses 7large enough, and providing passages of suitable size around the disk,the liquid in the bottle may be discharged in any suitable quantity, andwith or without shaking.

The moment the bottle is set upright the disk will fall back on itsseat, and cohesion will cause it to stick to its seat, so as to renderit absolutely impossible to lift by inserting any instrument into thevalve chamber, assuming that it were possible to insert such aninstrument. The passage 3 may be normally closed by a stopper 15.

Having thus described our invention, what we claim and desire to secureby Letters Patent is In a non-refillable bottle, the combination of astopple having a body portion fitting in the bottle and an end capportion forming an overhanging annular flange seating on top of thebottle neck, said body portion fitting within the bottle and havingcircumferential cement securing means therefor, said overhanging flangeprotecting the cement, said cap and body portion of the stopple dividedlengthwise into two complementary sections, l

one section longer than the other, with the longer section having acylindrical base portion against which the bottom of the shorter sectionabuts, and which cylindrical base portion is in continuation of theshorter section, said two sections above said base portion whenassembled inclosing a valve chamber, which chamber has a sinuousoutletupward through the cap and between the sections, said sinuousoutlet comprising a groove entirely within one section and one wall ofthe groove formed by the opposed plain surface of the opposite section,and an inlet through said base portion, and a flat disk valve in thevalve chamber having a substantial seating area over the mouth of saidinlet, and projections in the valve chamber and around the outletforming a support for said disk valve to maintain the outlet open whenthe bottle is inverted.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
